Embodiment Construction

[0022] A special machine processing method for a large seat ring: the processing method includes the following steps:

[0023] (1) if figure 1 As shown in the figure, a movable CNC seat ring processing machine is adopted, and the main part of the equipment includes a workbench 3, a column 1, a beam 2, and a tool holder 7;

[0024] (2) The rotating workbench of the equipment is installed on the assembly platform, and the workbench is leveled on the assembly platform with adjustable pad iron 4;

[0025] (3) Hang the split seat ring to the height of the machining stroke range of the machine tool, and on the support of the tooling, form the split seat ring 5 on the square box 6 to form a full circle;

[0026] (4) Adjust machine tool equipment, such as figure 2 As shown, adjust and align according to the existing benchmark on the seat ring 5 to ensure that the equipment is concentric with the seat ring;

[0027] (5) hoisting equipment column 1 and beam 2, tool holder 7 assembly...

Abstract

The invention discloses a machining process method of a special machine for large stay rings of water turbines. According to the process method, the stay rings are assembled and machined on an assembly platform by adopting movable vertical lathe machining and accompanying fixture appliances. The process method comprises the following steps: adopting special machine equipment with a movable workbench, and realizing disassembly and carrying for the equipment in a manner of disassembling and assembling the equipment with vertical columns, cross beams and a tool rest; meeting an installation accuracy need by adopting special movable equipment for installing and adjusting adjustment tools; enabling the stay ring to meet an equipment machining stroke in a manner of fixing and supporting the machined stay ring by a square box; aligning and machining the stay ring by virtue of the convenience of movability of the equipment, and avoiding frequent movement and alignment for the stay ring workpiece with a heavy weight; driving the vertical-column tool rest by the rotation of the workbench of the equipment to machine the fixed stay ring workpiece, thus realizing a one-time installation and all-dimensional machining process. The process method disclosed by the invention has the advantages of being novel and unique in machining process, reasonable and concise in process, controllable in machining quality, high in accuracy, and the like.

Description

Technical field: [0001] The invention discloses a process method for processing the seat ring of a large water turbine by a special machine. Background technique: [0002] The seat ring is an important flow part of the turbine, and it is also the main stress-bearing part of the embedded part. Seat rings of large hydraulic turbines mostly adopt a split structure, which are generally assembled into a full circle in the factory and then processed on a large vertical lathe. [0003] Large-scale seat rings are usually processed by general-purpose vertical lathes when the equipment capacity allows. The seat ring forms a complete circle on the vertical lathe table, and the turning process is carried out with the rotation of the vertical lathe table. After the vertical lathe processing is completed, it is disassembled into parts, and the screw holes are processed on the boring machine. Therefore, the processing of the entire seat ring needs to be completed with two sets of equipm...
